Basically, use vaddr_t for VA and paddr_t for PA. In addition, for variables
representing addresses, use paddr_t or vaddr_t, depending on the context.
For most arches, vaddr_t and paddr_t are equivalent to unsigned long. However,
the change was needed for exotic situations, like i386 PAE, were unsigned long
is not suitable for PA which are 64 bits long. As this required a complete
change of the function prototypes, all arches had to be adapted accordingly.
Core files from before this commit should still work with the new code; I did
not see any direct dependency between core's structure and kvatop/pa2off.
The change was compile tested for all arches, as it impacts all of them.

2. Don't malloc/free procbase/procbase2/lwpbase continuously. Keep track
of the size, and only do it if necessary.
3. Write a macro to malloc/realloc and set the size of members so that it
is done correctly. Previous open coded version in kvm_file.c always
set the length, which is incorrect.
4. Remove bogus check against INT_MAX.
5. use NULL to initialize pointers instead of 0.
kvm_getproc2() -> sysctl(KERN_PROC2)
kvm_getargv2() -> sysctl(KERN_PROC_ARGS, KERN_PROC_ARGV)
kvm_getenvv2() -> sysctl(KERN_PROC_ARGS, KERN_PROC_ENV)
Add new KVM_NO_FILES flag to kvm_open*() - set up enough state to
use the above calls without having to open any kernel files.
XXX: kvm_getprocs.3 and kvm_open.3 to be updated soon.
1) savecore will not access the dump or live-kernel directly. It
will always use the kvm-functions. Allowing it to work on kernels
that don't have a 1-1 PA-VA mapping.
2) the kvm-lib has some additional functions to accomplish 1
- kvm_dump_mkheader()
- kvm_dump_wrtheader()
- kvm_dump_inval()
3) the file formats of the dump generated by the kernel and the dump
generated by savecore have been changed. The file format now looks
like the format produced for 'normal' core dumps.
Ports not yet supporting the new kvm-format will be using libkvm.old/
savecore.old for the time being.
